CHARLES H. PERKINS, ()F PROVIDENCE, RHODE ISLAND, ASSIGNOR TO THE UNIONHORSESHOE COMPANY, OF SAME PLACE.

MACHINE FOR MAKING HORSESHO ES.

Specification forming part of Letters Patent No. 44,839, dated October25, 1864.

To all whom it may concern.-

Be it known that 1, CHARLES H. PERKINS, of the city and county ofProvidence, in the State oflthode Island,haveinventedanew and ImprovedMachine for Dressing the Blanks tor Horseshoes and I do hereby declarethat the following specification, taken in connection with the drawings,making a part of the same, is a full, clear, and exact desciiptionthereof.

Figure 1 is a perspective view with one side of the frame removed. Fig.2 is a View of the blank passing through the machine.

The machine represented in the accompanying drawings is designed toaccompany the machine described in other Letters Patent granted to me,of even date herewith, for improvements in machines for punching thenailholes in horseshoes, and is for the purpose of sh avin g ott' theblisters or protnberances which are raised upon one of the faces of theblank by the seiit s of punches with which the blank is punched.

As is fully described in the specification accompanyin g said patentreferred to, the punches do not pass entirely through the blank, butpenetrate the metal only to a depth equal to the thickness of the blank,thereby causing blisters to be raised upon the opposite side, which,when shaved off, will leave the bottom of the hole exposed.

It must be understood that the method which I have practiced with themost success in making horseshoes by machinery is to punch the holes andmake the creases for the heads of the nails before the blank has beenbent into the form of a shoe. The blank will as shown at 00, Fig. 2, andwill have upon one side a series of blisters, a a a a.

In the accompanying drawings, A is a wheel mounted 011 bearings whichrest in boxes be tween the uprights B B of the frame. This wheel has itsface smooth, and its bearings should be very strong, as its oflice is tosupport the blank while it is being acted upon by the cutter.

O is acornpound cutting and feeding wheel, located directly above thefriction-wheel A in boxes, which can be adjusted by means of the it isfed to the cutter, is pressed upon by the conical surface of thefeed-roller G and forced against the side of the cutter-wheel G, thesharp corner of which shaves off the blisters as they are brought insuccession to it, the llank being kept in the proper position by afriction-roller. I

WVhat I claim as my invention, and desire to secure by Letters Patent,is-

The combination of the compound feedingroller and cutter G O and thefriction-roller A, substantially as described, for the purposestherefore at the time that it is presented to this machine be in theform of a straight bar, i
